Possibly adding some kind of integrity check to the dex file will fix this?

Checking the integrity of the APK (and with it the classes.dex) is quite easy 
possible by the app itself by comparing the package-signature with a fixed one. 
I more fret about an app (you could download on certain sites...) which patches 
out the LVL from the dex-file in the dalvik-cache! Yes, you need a rooted 
phone, but who with cracked-apps doesn't have?
